i'm still thinking that you can get a 100% secure online wallet, you just need a isolated network and a desktop dedicated only to run the client

I am thinking the same way and it is the route I am taking. Fresh install of Linux on a dedicated machine, installed BTC Core and let it sycn up block chain. While it was syncing added firewall rules via IP Tables just to allow what is needed for basic functionality of the BTC client. I will only boot and sync when needed, and have passphrase protected the wallet. I will also keep copies of the encrypted wallet.dat file elsewhere for safekeeping.

If I begin to accumulate enough BTC where I think one wallet is too risky, I can always do the same with multiple machines. I already plan to keep a small amount of day-to-day BTC on my main desktop, so the dedicate box is just for longer term storage and will only need to be fired up on occasion. I suppose I could take it a step further and keep it offline like the guide, but I like the idea to just be able to send the BTC to my "spending" wallet when I have the need, or to easily fire it up and create additional receiving addresses when the need arises.

its a really great tutorial it was interesting to read i will definitely check it out when i will have some time and create a wallet even though i have a paper wallet lets hope it will be unhackable

Paper wallets are excellent. The security however, relay on how you generated the wallet.

My personal favorite-paranoid method is to roll a calibrated casino dice 99 times and covert the 99 digit base6 number into a bitcoin address and make sure none of the information is exposed to a computer that is ever connected to the Internet (Extra paranoid user can you pull the curtains as well while rolling the dice).

Yeah I agree paper wallet is the one safest method to save your bitcoins, You could try hardware or cold storage as well, Which is very much safe. Normally wallet security seems like one of the more major problems for the general population to use Bitcoins, especially considering the unability to recover stolen Bitcoins. It seems like Credit Card Fraud squared, if Bitcoins were to become really popular.

Just use a wallet website that allows you to enable 2FA security. Your wallet will not be hacked unless the hacker has an access to your phone or to the QR code that you scanned. Printing a paper wallet doesn't assure that you'll not get hacked in the future.

I am using coins.ph now and there's no hassle at all for I am using a 2FA security. They also enabled 2FA using email but now you can only do 2FA using your phone.

Not trying to be negative here, but this is really not the best advice to give. Unless you are using a solution like greenaddress that allows you to be in control of the private key then are website wallet solutions almost a sure way to loose your coins.

You only own bitcoins if you and only you are in control of the private key.

In any case, I consider it as the most fundamental skill for a bitcoiner to learn how to secure his own private keys.
